Paper presented at the ISRM International Symposium on In-Situ Rock Stress, May 10–12, 2016
Paper Number: ISRM-ISRS-2016-003
... Abstract The author has been involved in the stress state of earth's crust and analyzed the stresses through analytical solutions and finite element methods. For practical applications, he has developed various techniques for inferring the stress state in the earth's crust through utilization...

... eastern tectonic joint. As to the middle and south part of Sichuan-Yunnan rhombus block, the crust moves southeastward in the east while southwestward in the west. The results of two models with stronger rheological property in middle crust and in lower crust respectively have similar characteristics...

..., Chinese Earthquake Administration, Beijing, China ABSTRACT: Shear-wave splitting (seismic birefringence) shows that fluid-saturated microcracks throughout the Earth s crust are so closely-spaced they verge on fracturing and hence are critical-systems. Such criticality imposes fundamental new properties...

Importantly, the data sets are restricted to results from techniques that attempt to measure, without a priori assumption, the complete rock stress tensor and are presented as reported...

... the three-dimensional numerical modeling of in situ stress distributions in a limited seismic region of the Earth s crust. The model involves a vertical strike-slip planar fault that resides in the crust and reaches the Earth s surface. Stress distribution in faulted areas can be calculated and then used...

... at compression condition is presented for whole China continent, and the thermal thickness of the lithosphere is also calculated. The relative strength ratio of crust/mantle (SC/SM) in the vast region of Tibetan plateau is larger than 10, corresponding to a stronger crust but weak upper mantle. Off Tibetan...

..., initiating catastrophic failure. They can no longer activate h• charge carriers. As a consequence, pre-rupture signals will decrease in magnitude. 1 INTRODUCTION Whenlarge-scale tectonic stresses increase in the Earth crust beyond some critical threshold, faults can fail catastrophically and cause...
